TO ALL WHOM IT MAY-CONCERN:

Be it known that I, HARVEY WEBSTER, of' Cambridge, in the county ofiIiemo ille oud S tjate'of Vermont,

have inrentecl a new and improved Mode of Coupling and Unooupling Thills; and I do hereby declare that the following'is a full and exact description thereof," reference being had to the accompanying drawings, and the letters of reference rnarked thereon.

I Figure l,fperspec tive, showing coupling closed. Figure 2, longitudinal section, Coupling open. To enable others skilled iuthe art to make and use my iuventionkI will proceed to describe. its t: onstru tion and operation. V i v I make the thill-iron D, nxleiron E, and the clamp-F, in the usual way. I make the bolt, G, plain, that is, omitting the usual head, screw, aml'nut, and out itto in length flush with the outside of theears-h h, I then nddthe wedge-plnte A, the cap or bolt-holder B, and spring 0, to the axle-iron, inthe manner as shown, or any other, substantially the same. I v 1 I To uncouple the thil'ls from the vehicle, place the fingers underneath and behind the flange of wedge-plate A, and pull forward until the bolt-gap B uncovers the bolt G; at the sometime; push the bolt through the thill iron. The coupling is done in same manner,- pushing'the bolt Ginto thethill-irom,

I make the pluteA in the form of a, wedge, for the purpose of forcing'the thill-iron D-and boltv Gtightly together, thereby obviating all rattle ond'lwear ol' the ports mentioned.

The whole device to be applied to yehieles in the usual manner. What I claim as my invention, and desire to seonre by Letters Potent, isv The wedge-plate A, bolt-holder or cop B, and the spring 0,- as applied to thin-couplings, nn d operated either mover-WEBSTER.
